EDITED:
so lets make the question more clear
lets make it like this, if were gonna make 10 = b vv (sorry I meant to say 10, but I said 6 ;-;
3(10) - 4 + 6(10-9) = 30 - 4 + 6 = 26 + 6 = 32
= THIS EQUALS 32
Now lets do 9(b-6) - 4 which will be turned into 9(10-6) - 4 = 36 - 4 = THIS EQUALS 32
MY ANSWER IS YES (DONT ASK ME WHY IM WRITING IN CAPS (((: )
